  New Revision: 43278

  Log:
    ruby.c: gem_prelude to load rubygems
    
    * ruby.c (process_options): use gem_prelude instead of requiring
      rubygems directly when --enable=gems is given.
    * Makefile.in (DEFAULT_PRELUDES): always use gem_prelude regardless of
      --disable-rubygems.

 	* lib/mkmf.rb (have_framework): should append framework options to
 	  $LIBS, not $LDFLAGS.  the former is propagated to exts.mk when
 	  enable-static-linked-ext.
